Whole genome resequencing uncovers candidate genes related to plumage color in Yuexi frizzled feather chicken.

ABSTRACT: Yuexi Frizzled Feather Chicken (YFC), an indigenous breed in China noted for its curly feathers, primarily comprises yellow, white, and black plumage color strains. However, the genetic mechanism underlying the regulation of plumage colors remains unknown. In this study, whole genome resequencing was employed to systematically analyze and evaluate the genetic diversity of these three distinctive plumage color strains, as well as to screen and identify crucial genes related to the plumage color. Population genetic structure analysis revealed that the YFC could be divided into 3 plumage color populations, with the yellow-feathered chickens showing the highest genetic diversity, whereas the black-feathered chickens exhibited the strongest signatures of artificial selection.
